To ensure reliability and durability of the equipment, it is very important that the installation is carried out with the utmost care and attention. To avoid problems, such as temperature problems, noise levels, vibration, etc. the instructions set out in this manual must be followed and all installation work must be carried out professionally. 1.2 Position the generating set as low as possible in the vessel. As the generating set is already secured to the base frame by means of flexible engine mountings, the frame can be mounted directly to the vessel’s main structure. Whisper generating sets are standard equipped with a sound cover. The canopy has been designed to give effective sound insulation. For optimum sound and vibration dampening, the following factors should be considered. 1 Most important is the structure on which the generator is places to be stiff. Directly below the rubber mountings the structure should be supported vertically to the superstructure of the ship. 2 Avoid mounting the generating set in close proximity to thin walls or floors that may cause resonance. 3 Sound dampening is extremely poor if the generating set is mounted on a light weight flimsy surface such as plywood which will only amplify vibrations. If mounting on a thinner surface cannot be avoided, this should at least be reinforced with stiffening struts or ribbing. If possible, holes should be bored or cut through the surface to help reduce the resonance. Covering the surrounding walls and floors with a heavy coating plus foam will certainly improve the situation. 4 Never connect the base of the generating set directly to bulkheads or tanks. LOCATION Since Whisper generating sets have extremely compact dimensions, they can be installed in tight locations. Please consider that even almost maintenance-free machinery must still remain accessible. When selecting the location area in which to mount the generating set, make sure there is sufficient room to carry out any maintenance work. The unit must be easily accessible on the service side and on the distribution side to have access to the V-belt. Please also note that in spite of the automatic oil pressure sensor it is still essential that the oil level is checked regularly. Figure 1: Mounting of the Whisper generating set. EN / M-SC6/8/10 - 3000RPM / June 2010 X = wrong, V = OK 3 INSTALLATION 1.4 VENTILATION The generating set normally draws air from the engine room. Engine rooms with natural ventilation must have vent openings of adequate size and location to enable the generating set to operate without overheating. To allow an ample supply of air within the temperature limits of the generating set an opening of at least 100 cm2 is required. A "sealed" engine compartment must have a good extraction ventilator to maintain reasonable engine room temperatures. High temperature of intake air reduces engine performance and increases engine coolant temperatures. Air temperatures above 40°C reduce the engine power by 2% for each 5°C of rise. To minimise these effects the engine room temperature must not be more than 15ºC above the outside ambient air temperature. Apply a combination of ventilators, blowers and air intake ducting to meet the temperature limit. The air inlet ducts should run to the bottom of the engine room to clear fumes from the bilge and to circulate fresh air. Air outlets should be at the top of the engine room to remove the hottest air. An engine room blower should be used as an extraction ventilator to remove air from the engine room. In cases where it is impossible to meet the above mentioned temperature limit by using machine room ventilation, connections are to be made for an air inlet directly to the enclosure. With these connections the generating set can be directly connected to an air duct. 1.5 CONNECTIONS The generating set comes supplied with all supply lines and output cable (i.e. electric cables, cooling water connections, exhaust, fuel lines etc.) already connected to the engine and generator. The supply lines are fed through the capsule’s front base. The connections are marked as shown in fig. 2. All electrical connections, cable types and sizes must comply with the appropriate national regulations. Supplied cables are rated for ambient temperatures up to 70°C. If the cables are required to meet higher temperature requirements, they must be run through conduits. ATTENTION! Before working (installation) on the system read the section safety instructions Air inlets should be louvered, where appropriate, to protect the engine room and to protect the generating set from water spray. As an extra precaution, the fitting of a cowl ventilator with a cover box located as high as possible, is recommended. 4 June 2010 / M-SC6/8/10 - 3000RPM / EN INSTALLATION 01 02 03 04 05 06 08 09 10 11 12 13 Raw water inlet Ø19mm Fuel out Ø8mm Battery + 25mm2 Battery - 25mm2 Fuel in Ø8mm Expansion tank Ø8mm Bypass cooling water out Ø19mm (3/4") Bypass cooling water in Ø19mm (3/4") Exhaust hose Ø40mm AC power output Remote control Engine air intake Fig. 2: Connections M-SC6, 8 and 10. EN / M-SC6/8/10 - 3000RPM / June 2010 5 INSTALLATION 1.5.1 Fuel supply 1 FUEL TANK Fuel tanks should be made of appropriate material such as (stainless) steel or plastic. Steel tanks should not be galvanised or painted inside. Condensation can occur in metal tanks when temperature changes. Therefore, water accumulates at the bottom of the tank and provisions should be made for the drainage of this water. The tank will need a filling connection, a return connection and an air ventilation connection which will require protection against water entry. Some official regulations do not allow connection points at the base of the fuel tank; in this instance connections are to be made at the top of the tank with internal tubing down to a few cm above the bottom of the tank. 2 FUEL LIFT PUMP The generating set itself is equipped with a fuel lift pump; therefore the tank can be installed at a lower level than the generating set. The maximum suction height is 1 m. If the pump has to lift the fuel higher than one meter an external fuel lift pump must be installed. The control board is already prepared to connect an extra fuel pump. 3 FUEL PIPES When the tank is above the generating set (figure 3)`we recommend ending the return line on the top of the tank . When the return is on the top - in case of a leakage the return line cannot overflow because of siphoning. One will only need a fuel cock in the fuel supply line. 6 When the tank is below the generating set (figure 4) we recommend ending the return line on the bottom of the tank (A) below the inlet of the supply line to discharge under the lowest fuel level. This prevents air getting into the fuel line. Here also one needs a fuel cock only in the supply line Both supply and return fuel pipe lines should be appropriate material and 8 mm outer diameter tubing. The quality of the tubing of fuel pipes could be submitted to local regulations depending on the application of the vessel. The fuel pipes can be plumbed to the flexible hoses which are on the generating set and have a connection to fit to 8 mm pipe. This fuel lines fulfils CE standards and are according to ISO 7840 A2. It is important to avoid bends in the pipes, as they could trap air bubbles. The return pipe should never be connected to the suction pipe. Other consumers of diesel fuel, such as the propulsion engine and heaters, have to be connected to separate suction and return pipes. 4 FUEL FILTERS A fine fuel filter is installed which requires maintenance. Whisper Power advises to install an extra fuel filter/ water fuel separator near the fuel tank. Before starting your generating set for the first time follow the fuel system bleeding procedure in the user manual. June 2010 / M-SC6/8/10 - 3000RPM / EN INSTALLATION 1 Fuel return; 2 Fuel supply; 3 Prefilter / water separator (optional); 5 Fuel tank; Fig. 3: Fuel supply (fuel tank is above the generating set) 1 Fuel return; 2 Fuel supply; 3 Prefilter / water separator (optional); 4 Extra fuel lift pump (optional); 5 Fuel tank; Fig. 4: Fuel supply (fuel tank is below the generating set) EN / M-SC6/8/10 - 3000RPM / June 2010 7 INSTALLATION 1.5.2 Cooling Intercooling is based on a raw water pump, heat exchanger and water-injected exhaust. Cooling liquid in the internal cooling system is cooled in a heatexchanger by outboard water (raw water or seawater). After the raw water is warmed up in the heatexchanger it is dumped overboard by injecting it in the exhaust. The generating set should have its own sea water (coolant water) inlet and should not be connected to any other engine systems. A properly installed cooling system is critical to keep engine temperatures within an acceptable range. Ensure that the installation complies to the following installation instructions. 1 THE INTERNAL COOLING SYSTEM The internal cooling system should be filled with cooling liquid. (Refer to the user manual 2.5.12) When the engine becomes hot the liquid expands and the system is pressurised. After the pressure becomes too high the release valve in the filling cap on the manifold opens and the expanding liquid is pressed into the expansion tank that is in the delivery. Also the air in the system that is collected at the top of the manifold is released in this way. When the liquid cools down there will be under-pressure. Another valve opens and the liquid is sucked into the manifold again. This system works only when there is enough liquid initially. This has to be checked when commissioning the generator set. By filling up the expansion tank when necessary there will always be enough liquid in the system. The hose that is in the delivery has to be connected to the connection on the side of the filling cap. This hose is made of heat resistant plastic and is not sensitive for kinks. Fig.5: Expansion tank placement The tank has to be placed close to the generator. When it is mounted above the top of the manifold the liquid in the tank will be drained when the cap on the manifold is taken off. When keel cooling or radiator cooling is applied the system will not be pressurised. A cap without releasevalve should be applied. Refer to the special manual for these applications. 2 RAW WATER SUPPLY For raw water supply the following installation materials are required: -a skin fitting - a sea cock - a water strainer hoses and clamps. In order to keep the suction resistance in the line at a minimum, the sea water intake system (i.e. sea cock, tru-hull fitting, inlet filter, etc.) must have an inner diameter of at least: Model Minimum inner diameter M-SC6 – 3000 rpm 19 mm (3/4") M-SC8 – 3000 rpm 19 mm (3/4") M-SC10 – 3000 rpm 19 mm (3/4") Fig. 6: Internal cooling system 1 Water level 2 Water/exhaust separator 3 Seacock 4 Waterlock 8 5 Air vent; 6 Water strainer; 7 Seacock. June 2010 / M-SC6/8/10 - 3000RPM / EN INSTALLATION The suction hose should be kept as short as possible. Raw water plumbing should avoid bends as much as possible. Restriction of raw water flow, caused by kinked hoses, undersized pipes or connections, will reduce the engine cooling capability. This is the main cause for overheating of an engine. After running the generating set for the first time, check the coolant flow rate using a stopwatch and by holding a pail of a known volume under the wet-exhaust outlet. The flow rate should be according to the data in the user manual. Install the water strainer in a well accessible position, (refer to fig. 6-6) 5 cm above the waterline. 5 SIPHON BREAKER (AIR VENT) When the point of water injection is below the waterline, then -when the engine is stopped -there is a risk that the cooling water may enter the engine as a result of siphoning. To avoid this happening, the generating set is designed to accommodate a siphon breaker (air vent). In the standard delivery the connections are bypassed. See figure 8. 3 INSTALLATION OF THROUGH HULL FITTING It is good practice for yachts to use a hull inlet fitting with an integrated strainer (water scoop). For propulsion engines in motorboats the water scoop is often mounted against the sailing direction to induce more water intake for cooling. This should not be done in the case of a generating set! When sailing at higher speeds, water will be forced into the inlet and your generating set will overflow! SAILING DIRECTION Fig. 8: Bypassed siphon breaker connections FLOW DIRECTION SAILING DIRECTION FLOW DIRECTION Fig. 7 Installing water intake On motorboats and on sailing boats the water scoop for a generating set should be fitted with the opening faced backwards to prevent water being forced in during sailing. Use a sealant when mounting the skin fitting. 4 WATER STRAINER Use an appropriate water strainer with connections of the following dimensions: Model M-SC6 – 3000 rpm M-SC8 – 3000 rpm M-SC10 – 3000 rpm Inner dimensions 19 mm (3/4") 19 mm (3/4") 19 mm (3/4") EN / M-SC6/8/10 - 3000RPM / June 2010 Hoses with the following inner diameter should be used: Model M-SC6 – 3000 rpm M-SC8 – 3000 rpm M-SC10 – 3000 rpm Inner dimensions 19 mm (3/4") 19 mm (3/4") 19 mm (3/4") If the generating set cannot be mounted such that the bottom of the generating set is placed above the waterline, an air vent must be installed. See figure 9. Extend the water hose of the by-pass 60 cm above waterline and install an air vent. Ideally, the air vent should be mounted above the yacht keel center line (i.e. to minimize the influence of swaying on the water intake). Fast motorboats will lay deeper when sailing at large speed and can cause pressure on the waterinlet. This should be avoided to prevent fleeding the engine. If the air vent is clogged the water hoses will not be vented when the generating set has stopped and water can be forced into the engine. This leads to immediate engine problems and eventually severe damage! 9 INSTALLATION DAMAGE CAUSED BY THE INGRESS OF WATER IN THE ENGINE IS NOT COVERED BY WARRANTEE considerably, so that a rubber exhaust hose can be used and the level of noise is reduced as well. OPEN Figure 9: Siphon breaker connected Fig. 11: Whisper Power siphon breaker On the valve is a little hose to drain a little water that could be spilled from the valve. This hose should go down and may not end under water, because it should ventilate air into the valve to break the siphoning. 1 STANDARD EXHAUST SYSTEM INSTALLATION The generating set exhaust system must remain completely independent and separate from the exhaust system of any other engine on board. A water lock prevents the generating set from being flooded by cooling water and should be installed as close to the generating set as possible. The lock must be large enough to hold the entire water volume held in the hose from the top of the goose neck to the water lock. The water lock must be installed at the lowest point of the exhaust system (ref. to fig. 10-1). The exhaust hose must have an inner diameter of 40 mm (1⅝”) no less, no more. The exhaust system must be installed so that the back pressure inside the exhaust does not exceed 0.07 bar (1psi – 70 cm watercolumn) and total length from the genearot to the top of the goose neck or or water/separator does not exceed 3m (10 ft.). (Refer to paragraph 5.4.3 of the user manual). OPEN Fig 10: Wrong siphon breaker hose routing Check the air vent at regular intervals. Open, clean and lubricate the valve as required. 1.5.3 Exhaust system Water is injected in the exhaust system of the generating set. In this way the cooling water that has passed the heat exchanger is mixed with the exhaust gases. Temperature and volume of the gases are thereby reduced 10 The exhaust hose descends from the capsule to the water lock. Then the hose rises via the "goose neck" to the through-hull exhaust outlet, situated minimum 5 cm (2") above the water line (ref. to fig. 12-5.) The "goose neck" must be vertical and situated preferable along the ship’s keel center line. If the generating set is mounted less than 60 cm (24") above the waterline, a "goose neck" must be installed to prevent the engine from overflowing. It is recommended to install an extra muffler close to the through-hull fitting.

In order to reduce the noise level of the generating set to a minimum, an option to reduce the exhaust noise further (especially exhaust water splashing) is an exhaust/water separator. The exhaust/water separator allows the cooling water to be ejected through a line separate from the exhaust fumes and also functions as a goose neck to prevent water from flooding the engine. If the exhaust/water separator is mounted more than 60 cm above the water level an additional goose neck is not required. If the through-hull exhaust outlet has to be mounted far from the generating set (Total length of the exhaust piping from generator to top of goose neck (water separator) is more than 3m.), an exhaust/water separator must definitely be installed. The sea water from the separator must then run down along the shortest possible path to the through-hull outlet. Only after the exhaust/water separator the exhaust hose may have a length of over 7,5 m if the exhaust hose 5 diameter is also increased from Ø 40 mm (1 /8”) to 51 mm (2”) in order to reduce the back pressure (ref. to figure 12) However watertraps should be avoided as the fumes still contains water and this should not accumulate in bents (refer to figures 15 and 16). An additional outlet exhaust muffler close to the hull outlet will help further to reduce noise emission. OK! Fig.15: Water trap in exhaust system WRONG! Figure 16: Water will collect in the hanging bend of the exhaust gas hose and will cause back pressure EN / M-SC6/8/10 - 3000RPM / June 2010 13 INSTALLATION If the generating set and the exhaust system have been installed correctly, neighbouring boats will not be disturbed by generating set noise, With the "super silent" exhaust system, generating set noises are almost inaudible. For optimal noise reduction, the sea water outlet from the exhaust/water separator (center outlet on the unit) should be installed below the water level to eliminate noisy splashing of the effluent sea water. The through-hull outlet for the exhaust fumes should not direct the fumes directly toward the water surface as this will cause excessive noise (ref. to fig. 17). Do not direct the outlet directly toward the water surface. WRONG! OK! 1.5.4 Digital Diesel Control system (12 Volt) 1 DIGITAL DIESEL CONTROL SYSTEM The electrical control system is standard in 12 Volt with negative earth. Non- earth return is available as an option for aluminium vessels to prevent corrosion. All electrical wiring has been prepared on the generating set to the control panel prior to despatch from the factory. The engine is controlled by a very advanced microprocessor based system: Digital Diesel Control. The “black box” containing the microprocessor is located on top of the alternator. A local control panel is on the generating set. Remote control A remote control panel also containing a microprocessor is in the delivery. A 15 m intermediate 8-pole communication cable is in the standard supply as well (refer to fig. 18). If necessary an optional longer (up to 30m / 100ft) intermediate cable can be connected if the standard length does not suit the required distance. When a longer distance than 30m / 100ft is required, consult the Whisper Power service department for advice. Figure 17: Outlet direction Fig. 18: Remote control cable 14 June 2010 / M-SC6/8/10 - 3000RPM / EN INSTALLATION One can mount the control panel after drilling a hole in the dashboard using the plastic cover. Refer to the dimensional drawing in paragraph 3.5. The panel without the plastic cover fits the Mastervision modular panel system. More remote control panels (slave panels) can be put in parallel by using the modular connectors on the back of the units. As a slave one can use the same panel offering all functions again. It is also possible to use an old or new type slave panel only to start and stop the generator. Old type remote panels and system panels can be connected by means of the green connector. Pay attention to the colour codes as indicated in fig. 19 when fitting cable to the green connector. Some software versions in old system panels (supplied before May 2004) could conflict with the software in the DDC and an update of the software of the system panel could be necessary. When this is the case consult to the Whisper Power service department for advice. Acoustic alarm or warning lamp One can connect an external max.150 mA relay to generate an acoustic warning or applying a warning lamp etc. Be aware of polarity as some relays has a diode inside and should be connected plus to plus en minus to minus as indicated. Refer to fig. 19. Connection for emergency stop / fire alarm switch To connect an emergency stop button or to stop the generator automatically in case of a fire alarm, you can use the bypass connection between fastons J7 and J18 on the backside of the local control panel. See fig. 20. To do so, remove this bypass connection and then replace it by an emergency switch or a potential free fire alarm switch with normally closed contacts. Remove bypass between J7 - J18 When using the factory settings, installation is very simple: just plug the remote cable into the remote and the generator is ready to use.

Using the auto-start/stop (interval) mode the generator can start unexpectedly. When working on the electrical system, the 3 Amp fuse must be removed from the control panel and the battery plus cable must be removed from the battery. Fig. 19 Remote box terminals The Whisper Power Digital Diesel Control system offers several options for automatic starting and stopping. Access to this menu and other menus could be blocked. For blocking and setting up this options refer to the APPENDIX of the DDC users manual. EN / M-SC6/8/10 - 3000RPM / June 2010 15 INSTALLATION One of these options is to monitor a second battery (not being the starter battery) to start the generator automatically when the voltage of this battery drops below a certain setting. Other names for this second battery are “auxiliary battery”, “service battery”, ”users battery” or “consumers battery”. We will refer to this battery as “the second battery”(BAT2). In some menus the starter battery could be indicated as “the first battery” (BAT1). A sense wire to monitor the second battery should be connected (attention polarity!) to the connector on the back of the remote panel. Refer to fig. 17. The sense wires must be connected directly on the second battery before a main switch and be protected by a 3 Amps fuse. (Monitoring the generator starter battery does not require an extra sense connection) Settings When one want to apply other settings than the factory settings refer to the DDC users manual, especially to the APPENDIX. 2 STARTER BATTERY For starting, the Whisper generator requires a 12V starter battery with the following capacity: Model M-SC6 – 3000 rpm M-SC8 – 3000 rpm M-SC10 – 3000 rpm Minimum capacity 60 Ah 60 Ah 60 Ah The generating set can be connected with the main engine battery or have its own battery. We strongly recommend the use of a separate battery for the generating set and to keep the wiring system for the propulsion engine and the domestic DC supply system 16 completely separate separate batteries. and individually connected to Fig. 21 Starter battery However, the negative of all the batteries on the vessel should be interconnected (when on earth) to avoid difference in the voltage level of the earth on different places causing trouble to electronic devices which might be in the system. The above recommendation is not valid for ships having the starter battery of the propulsion engine or other auxiliary equipment positive grounded. When this is the case an expert should be consulted. A battery switch may be used. The starter battery is charged by the standard internal charger in the alternator. An additional battery charger will help to keep the battery in good condition when the generating set is not used. A battery charger is not included in the standard supply. A high efficiency battery charging unit can be ordered from Whisper Power which is able to charge both the ship’s main battery and the starter battery. Also a small charger can be used to charge the starter battery only, such as the IVO SMART 12/10. A battery switch and a charger are included in the battery installation kit, art. no. 50230210 (70Ah). June 2010 / M-SC6/8/10 - 3000RPM / EN INSTALLATION 3 OTHER RECOMMENDATIONS AND WARNINGS The battery should be secured for seagoing conditions and the terminals should be insulated. For extra safety the battery can be enclosed in a wooden, plastic, Fiberglas etc. (non metal) box. Even when the earth return system is applied a negative battery cable should be used and the vessel should not to be used as a conductor. In the negative battery cable a 250 Amp starter battery switch could be applied to switch off the battery. The battery cables are supplied in a standard length of 1.5 m, if longer cables are required a larger cross sectional area should be considered to compensate for voltage reduction. When two batteries are used in series to provide a 24 Volt supply system, never take off 12 Volt (starting) power from one of these batteries. This will result in severe damage to the batteries within a short time. Disconnect the battery leads if electrical welding is to be carried out, otherwise damage will be caused to the diodes of the alternator. As explosive hydrogen gases are discharged during charging, the battery should be located in a well ventilated room. Ensure that the supplied battery cable connectors are properly fitted and never remove during or shortly after charging as sparking can occur, which may ignite the hydrogen gasses. 1.5.5 AC power system (230 Volt) Before working (installation) on the system read the sections on safety in the user manual. Be sure that all electrical installations (including all safety systems) comply with all required regulations of the local authorities. All electrical safety/shutdown and circuit breaking systems have to be installed onboard as the generating set itself cannot be equipped with such equipment for every possible variation. The vessel’s power supply system should be suitable and safe for the AC voltage which is applied and the power that will be generated. Special attention has to be paid on dividing the system in branches which are fused individually. It is absolutely essential that each and every circuit in the on-board electrical system is properly installed by a qualified electrician. 1 FUSE An output fuse (from the generating set to the system) should be installed to protect the installed electrical system. The following maximum output current applies for each separate phase: Model M-SC6 – 3000 rpm M-SC8 – 3000 rpm M-SC10 – 3000 rpm Maximum output current 25 Amp 32 Amp 40 Amp The fuses must be of the slow reacting type. For electrical motors connected to the system, a motor protection switch must be installed. EN / M-SC6/8/10 - 3000RPM / June 2010 17 INSTALLATION 2 GROUNDING The AC alternator windings are not grounded. Measures against earth insulation failures are often subject to local regulations. The housing of the alternator and all other metal parts are grounded. For safety reasons connect the main ships ground to negative point of the generating set start battery. When an ungrounded return DC system or positive grounded DC system is applied the battery negative should not be connected to the main ships ground. To make a connection between “neutral” and “ground” could be necessary as part of a specific insulation failure protection system. Small pleasure craft in Europe is submitted to The Recreational Craft Directive 94/25/EC. The guidelines of this directive refer to (ISO 13297). When the installation comply to this standard the “neutral” and “ground” should be connected on the generating set by connecting the blue (neutral) wire with the terminal on which the yellow/green wire is connected. WARNING In all situations the transfer switches between shore, inverter and generator should switch all connections, the phase line (L) as wel as neutral (N). Of course this is the case when using a Masterswitch. Be aware that insulation protection systems can be different for different applications and even within the ship there could be different standards for different spaces. We did refer to the Recreational Craft Directive that applies to pleasure craft up to 24 m of length. Sometimes one has to comply with other standards such as the rules of certification societies like Lloyds Register of Shipping or Veritas, regulations for the protection of personal, building legislation, etc. It is of the greatest importance to have expert advice on this issue. 18 For safety reasons connect the main ships ground to negative point of the generating set start battery. When a ungrounded DC system or positive grounded DC system is applied the battery negative should not be connected to then main ships ground. 3 CABLE For the power cable we recommend the oil resistant cable with the following cross sectional area: Model M-SC6 – 3000 rpm M-SC8 – 3000 rpm M-SC10 – 3000 rpm cross sectional area 3x4 mm² (5m. included) 3x4 mm² (5m. included) 3x10 mm2 (not included) For very long cables it is recommended to apply cables with a larger cross section than the mentioned above. 4 TRANSFER SWITCH A power source selector switch much be installed between the generating set and the ship’s electrical supply system. This switch must ensure that all AC consumers can be switched off at once. This switch should also be installed to keep the generating set and shore (grid) power systems separate. Transfer switches - to switch over from shore to ship or from generating set to inverter - should be well designed to switch over all wires including neutral (and not only phases or line) and there should be provisions with the aid of timers to prevent relays from chattering. Whisper Power advises the installation of a Masterswitch as the power source selector. This works automatically when the generating set is not running the input remains in the shore position and as soon as the generating set is running the Masterswitch switches automatically after 10 seconds delay time over to the generating set position. June 2010 / M-SC6/8/10 - 3000RPM / EN INSTALLATION SPECIFICATIONS 2 INSTALLATION SPECIFICATIONS 2.1 INSTALLATION TABLE 6 Check if an AC breaker is installed before or after the power source selector. When there is only a circuit breaker, use it to disconnect the generating set from the grid. 7 Check all DC connections, check if the battery switch/ circuit breaker is closed. 8 Open the fuel valve and bleed the fuel system. Check if there are no air leaks in the fuel supply line, and check if the lift of the fuel is less than 1 meter (3 ft). Check if there is no air in the water fuel separator. Check if the air intake in the canopy is not blocked. 1 Mount the generating set directly, without additional vibration dampers, on a solid surface. 2 Connect the (sea) water inlet to the strainer. 3 Connect exhaust system. 4 Connect a siphon breaker or ‘air vent’ into the cooling circuit, if necessary. 5 Connect ‘fuel supply line’ to the water separator/ fuel filter. 9 6 Connect ‘fuel return line’ to the fuel tank. 10 Check the oil level and color of the oil. Check the coolant level 7 Connect remote panel (just plug in). 8 Connect the AC cable from the AC box to the power source selector or Masterswitch. 11 To bleed the fuel system push the startbutton on the local control (not on the remote) and hold at least 5 seconds and as long as necessary to bleed the system. 9 Connect plus and minus from the 12V starter battery to the battery cables. 12 Start the engine by pushing the start button. 10 Install a Whisper Power battery charger. (optional) 2.2 COMMISSION TABLE 13 Check when the generating set is running, the delay of 5 to 10 seconds in the power source selector transfer. 1 Check if a siphon breaker (air vent) is necessary and has been installed 14 Check voltage and frequency under ‘no load’ conditions. 2 Open the seawater inlet valve and check all water connections. Check if the strainer is installed above the seawater level. 15 Check voltage and frequency under ‘full load’ conditions. 3 4 5 Check if the exhaust system is properly installed. Check maximum length of exhaust hose, diameter of exhaust hose, position of the waterlock, maximum lift. Also check the minimum required height of 60 cm (24”) above sea level of the exhaust loop (goose neck). Open the seawater outlet valve and check all water connections. Check the AC cables and the grounding. EN / M-SC6/8/10 - 3000RPM / June 2010 16 Check if the battery charger of the generating set is working (max. 14.5 Volt). 17 Close the sound shield and check the noise level. 18 Stop the generating set and check the engine again for leakages of oil, fuel or water.

Electronic governer. The models mentioned above are equipped with an electronic governor in addition to the mechanical governor that is on other Whisper models. A governor keeps the speed (RPM=Rotations Per Minute) of the engine at a fixed value. The RPM of the engine correlates with the frequency of the electrical output (3000 RPM =50 Hz) of the alternator. Under full load the RPM of the Whisper models that has only a mechanical governor can drop 75 RPM (=2.5 Hz) at full load and will go further down or collapse when further loaded. However the engines with the electronic governor will keep the RPM and frequency at the set value. As the voltage is related to the frequency, the voltage will be more stable as well. The RPM represents power and the alternator performs better as well on a higher speed. Whisper models with an electronic governor will bring more power. So the electronic governor offers three advantages: a more stable frequency and voltage and more power. EN / M-SC6/8/10 - 3000RPM / June 2010 The electronic governor system contains 2 parts: 1 The actuator controls the engine speed. This actuator replaces the standard hold solenoid that is on all other mechanical controlled Whisper engines. The actuator controls the RPM directly on the fuel rack inside the fuel pump without levers and other mechanical transmissions. 2 A microprocessor keeps the speed at the set value by controlling the actuator. The microprocessor is programmed at the Whisper Power factory and many parameters are set to perform well. It should not be necessary to make adjustments. When adjustments are necessary this can only be done with the help of an interface to a computer and special software to get access to the microprocessor. The Whisper Power electronic governor does not need a pickup device in the flywheel housing that counts the passing tooth of the flywheel and determines the exact RPM of the engine, because the processor uses the 50 Hz of the AC output voltage as a reference. 27 INSTALLATION SPECIFICATIONS 3.4 AC WIRING DIAGRAM 230V / 50HZ STATOR GREEN (1) EXCITATION WINDING CAPACITOR GREEN (2) EARTH AND NEUTRAL NOT CONNECTED RED (3) 230V / 50Hz RED (11) MAIN WINDING BLACK (11) DDC/ct-1 ROTOR BROWN L1 YELLOW/GREEN PE BLUE N BLACK (4) BLUE (33) MAIN WINDING BROWN (33) RED (3) DDC/AC-1 BLACK (4) YELLOW/GREEN EARTH AND NEUTRAL CONNECTED Fig. 27: AC wiring diagram 28 June 2010 / M-SC6/8/10 - 3000RPM / EN DIAGRAMS & DRAWINGS 3.5 REMOTE CONTROL PANEL DRAWINGS Figure 28: The remote panel comes in a carton that can be used as a template to drill the mounting hole.
